This quiz contains 5 questions

  1. 1

    What is the time complexity of insertion in a singly linked list when adding to the tail with a maintained tail pointer?

    • AO(1)
    • BO(n log n)
    • CO(log n)
    • DO(n)
  2. 2

    In a binary search tree, which traversal method visits nodes in ascending order?

    • APostorder
    • BBreadth-first
    • CPreorder
    • DInorder
  3. 3

    Which of the following sorting algorithms has a worst-case time complexity of O(n²)?

    • ABubble Sort
    • BQuick Sort (with optimal pivot)
    • CMerge Sort
    • DHeap Sort
  4. 4

    What is the primary difference between a singly linked list and a doubly linked list?

    • AA singly linked list allows O(1) random access, while a doubly linked list does not
    • BA singly linked list has a head pointer, while a doubly linked list does not
    • CA singly linked list can only be traversed forward, while a doubly linked list can be traversed in both directions
    • DA singly linked list can contain more elements than a doubly linked list
  5. 5

    Which of the following is NOT a property of a binary search tree?

    • ABoth the left and right subtrees are also binary search trees
    • BAll nodes must have exactly two children
    • CThe left subtree of a node contains only nodes with keys less than the node's key
    • DThe right subtree of a node contains only nodes with keys greater than or equal to the node's key
